John and Randy, maybe we're again getting tangled-up in the semantics of ineptly written/translated manuals. If a receiver couldn't send low bass info(including LFE)from the "small" speakers and LFE channel(a separate channel, none of it being in the mains, center or surround channels) to the mains set "large" when there wasn't a sub this would seem to defeat the purpose of bass management. Looking at p.35 of the 2805 manual it somewhat clumsily states: "When the subwoofer set to "NO", the bass sound is output from the speaker set as "Large"." For the 630 at p.24 when the mains are set "Large" and the sub "None": "When this option is selected all bass information will be routed to the front left/right "main" speakers."
